[0002] A motorcycle's seat lock is used to unlock or lock the seat assembly, the seat cable is used to control the opening and closing of the seat, and the seat strap is used for the rear passenger to grip. In existing technology, the motorcycle's seat lock, seat cable, and seat strap are fixedly connected to the frame through their respective mounting points. This requires multiple mounting points on the frame for installation, resulting in a large number of mounting points on the frame and occupying a significant amount of space, leading to poor space utilization of the frame. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, the purpose of this application is to provide a motorcycle with a high space utilization rate of the frame.

[0004] To achieve the above objectives, this application adopts the following technical solution:

[0005] A motorcycle includes a frame, a running gear, a power unit, and a seat assembly. The frame includes a main frame and a subframe located behind the main frame. The running gear includes a rear wheel located at least partially below the subframe. The power unit is supported by the main frame and driven to the rear wheel. The seat assembly includes a main seat located above and fixedly connected to the subframe. The seat assembly also includes a sub-seat. The frame further includes an auxiliary mounting bracket located behind and fixedly connected to the subframe. The sub-seat is also at least partially located above and abuts against the auxiliary mounting bracket. The seat assembly also includes a seat lock for unlocking or locking the seat assembly, a seat cable for controlling the opening and closing of the main seat, and a seat strap for a rear passenger to grip. The seat lock, seat cable, and seat strap are all fixedly connected to the auxiliary mounting bracket.

[0006] Furthermore, the auxiliary mounting frame has a strap fixing part, and both ends of the seat cushion strap are respectively connected to the strap fixing part, which is located at the front end of the auxiliary mounting frame.

[0007] Furthermore, there are two strap fixing parts, and the two strap fixing parts are distributed along the width direction of the motorcycle.

[0008] Furthermore, the auxiliary mounting bracket is also provided with a cable fixing part for fixing the seat cable and a seat lock fixing part for fixing the seat lock. The cable fixing part is located to the right of the cable fixing part, and the seat lock fixing part is located below the cable fixing part.

[0009] Furthermore, the frame also includes a rear support bracket, which is located behind the subframe and fixedly connected to it, and a secondary seat is located above the rear support bracket and fixedly connected to it.

[0010] Furthermore, a seat cushion support point is formed on the auxiliary mounting bracket. The seat cushion support point is located behind the strap fixing part, and the sub-seat cushion abuts against the auxiliary mounting bracket through the seat cushion support point.

[0011] Furthermore, there are two seat support points, and the two seat support points are distributed along the width direction of the motorcycle.

[0012] Furthermore, the auxiliary mounting bracket is provided with several weight-reducing holes, which are located between the strap fixing part and the seat cushion support point.

[0013] Furthermore, the auxiliary mounting bracket also includes an electrical component fixing part located behind the seat support point.

[0036] To enable those skilled in the art to better understand the solutions of this application, the technical solutions in specific embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0037] like Figure 1 As shown, a motorcycle 100 includes a frame 11, a body panel 12, a running gear 13, a power unit 14, and a suspension assembly 15. The frame 11 forms the basic framework of the motorcycle 100, primarily providing support for other components. The body panel 12 is at least partially connected to the frame 11, protecting the internal parts of the motorcycle 100. The running gear 13 is at least partially disposed below the frame 11 and connected to it via the suspension assembly 15. The running gear 13 includes a front wheel 131 and a rear wheel 132. The power unit 14 is at least partially connected to the frame 11 and is drive-driven to the rear wheel 132. The power unit 14 generates driving force to propel the motorcycle 100. To clearly illustrate the technical solution of this application, the following are also defined: Figure 1 The front, rear, left, right, top, and bottom sides are shown. It is understood that in this embodiment, the length direction refers to the front-to-back direction of the motorcycle 100, the width direction refers to the left-to-right direction of the motorcycle 100, and the height direction refers to the up-down direction of the motorcycle 100.

[0038] like Figure 2 As shown, the frame 11 includes a main frame 111 and a subframe 112 located behind the main frame 111. The main frame 111 and the subframe 112 are fixedly connected, thus forming the main frame of the motorcycle 100 to support other components of the motorcycle 100. The power assembly 14 includes an engine 141 (see reference). Figure 1 The engine 141 is mounted on and fixedly connected to the main frame 111. The motorcycle 100 also includes an exhaust assembly 16 connected to the power assembly 14. The exhaust assembly 16 is mainly used to exhaust the exhaust gases generated by the power assembly 14. The exhaust assembly 16 includes an exhaust pipe 161 and a muffler 162. At least a portion of the exhaust pipe 161 extends along the length of the motorcycle 100, and the front end of the exhaust pipe 161 is connected to the engine 141. The rear end of the exhaust pipe 161 is fixedly connected to the muffler 162. The muffler 162 is located at the end of the exhaust pipe 161 and is directly connected to the outside. The muffler 162 is mainly used to reduce the noise generated when exhaust gases are discharged. (See reference...) Figure 1 The seat assembly 22 includes a secondary seat 222 located at the rear of the frame 11, and a muffler 162 located below the secondary seat 222. Viewed along the width of the motorcycle 100, the muffler 162 is located between the rear wheel 132 and the secondary seat 222.

[0039] like Figure 3As shown, in one embodiment, the exhaust pipe 161 extends towards the rear of the motorcycle 100, and during its extension towards the rear of the motorcycle 100, it divides into a first exhaust pipe 1611 and a second exhaust pipe 1612. The first exhaust pipe 1611 and the second exhaust pipe 1612 are two independent exhaust channels, and the first exhaust pipe 1611 and the second exhaust pipe 1612 are distributed along the width direction of the motorcycle 100. Specifically, the first exhaust pipe 1611 includes a first port 1611a and a second port 1611b, which are distributed along the height direction of the motorcycle 100; the second exhaust pipe 1612 includes a third port 1612a and a fourth port 1612b, which are distributed along the height direction of the motorcycle 100. The muffler 162 includes a first muffler 1621, a second muffler 1622, a third muffler 1623, and a fourth muffler 1624. The first muffler 1621 is fixedly connected to a first port 1611a, the second muffler 1622 is fixedly connected to a second port 1611b, the third muffler 1623 is fixedly connected to a third port 1612a, and the fourth muffler 1624 is fixedly connected to a fourth port 1612b. Viewed along the height of the motorcycle 100, the first muffler 1621 and the second muffler 1622 at least partially overlap, and the third muffler 1623 and the fourth muffler 1624 at least partially overlap, so as to make the structure between the various mufflers 162 more compact.

[0040] More specifically, the body panel 12 includes side skirts 121 located on both sides of the motorcycle 100, and the frame 11 also includes footrests 113 located behind the main frame 111, the footrests 113 being fixedly connected to the subframe 112. Optionally, the footrests 113 are also at least partially located on both sides of the muffler 162, and when viewed in the width direction of the motorcycle 100, the footrests 113 and the muffler 162 at least partially overlap. Further, the side skirts 121 are also at least partially located on both sides of the muffler 162, and similarly, when viewed in the width direction of the motorcycle 100, the side skirts 121 and the muffler 162 at least partially overlap.

[0041] As one possible implementation, the side guard plate 121 is fixedly connected to the footrest bracket 113. The side guard plate 121 located on one side of the motorcycle 100 is fixedly connected to the first muffler 1621 and the second muffler 1622. The side guard plate 121 located on one side of the motorcycle 100 is fixedly connected to the third muffler 1623 and the fourth muffler 1624. There are two footrest brackets 113 and two side guard plates 121, and both footrest brackets 113 and two side guard plates 121 are along the width of the motorcycle 100. The mufflers 1621, 1622, 1623, and 1624 are directionally distributed such that they are all fixedly connected to the subframe 112 via side guards 121. The first and second mufflers 1621 are fixedly connected to one side guard 121, and the third and fourth mufflers 1623 are fixedly connected to the other side guard 121, preventing the mufflers 162 from shaking during motorcycle 100 operation. The muffler 162 also includes multiple muffler mounting plates 1625, including a first mounting plate 1625a distributed along the width of the motorcycle 100 (see reference). Figure 5 ) and second mounting plate 1625b (refer to Figure 5 The first mounting plate 1625a is located between the first muffler 1621 and the second muffler 1622, and fixes the first muffler 1621 and the second muffler 1622 together. The second mounting plate 1625b is also located between the third muffler 1623 and the fourth muffler 1624, and fixes the third muffler 1623 and the fourth muffler 1624 together. In addition, the muffler mounting plate 1625 is also fixedly connected to the footrest bracket 113, so that the muffler 162 can be fixedly connected to the subframe 112 through the footrest bracket 113. With the above configuration, the present application has four mufflers 162, and each of the four mufflers 162 is connected to the exhaust pipe 161 through a port, thereby improving the exhaust efficiency of the exhaust pipe 161. The four mufflers 162 can also achieve the effect of diverting the exhaust, reducing the noise generated by the motorcycle 100 when it exhausts, and improving the driving comfort of the driver. It should be noted that the exhaust pipe 161 in this application refers to the rear exhaust pipe 161 located behind the muffler at the bottom of the motorcycle 100, and the muffler 162 in this application refers to the tailpipe located at the rear of the motorcycle 100.

[0042] like Figure 4As shown, further, a transverse plane 101 perpendicular to the length direction of the motorcycle 100 is defined. Along the length direction of the motorcycle 100, the projections of the first muffler 1621, the second muffler 1622, the third muffler 1623, and the fourth muffler 1624 onto the transverse plane 101 are respectively the first projection, the second projection, the third projection, and the fourth projection. Since the muffler 162 in this application is basically cylindrical, the center of the first projection is the projection of the axis of the first muffler 1621 onto the transverse plane 101. Similarly, the same applies to the second muffler 1622, the third muffler 1623, and the fourth muffler 1624. The line connecting the center of the first projection and the center of the second projection is defined as the first connecting line 201, and the line connecting the center of the third projection and the center of the fourth projection is defined as the second connecting line 202. An angle α is formed between the first connecting line 201 and the second connecting line 202, and the angle α ranges from 16° to 24°; further, the angle α ranges from 18° to 22°; in this embodiment, the angle α is 20°. With the above settings, if the included angle α is too small, the second muffler 1622 and the fourth muffler 1624 located below may interfere with the rear wheel 132 of the motorcycle 100, affecting the normal driving of the motorcycle 100; if the included angle α is too large, the second muffler 1622 and the fourth muffler 1624 located below will protrude too much on both sides of the motorcycle 100, so that in the event of a motorcycle crash, the second muffler 1622 and the fourth muffler 1624 may come into direct contact with the ground, causing damage to the second muffler 1622 and the fourth muffler 1624. Therefore, the included angle α setting in this application can not only avoid the second muffler 1622 and the fourth muffler 1624 from affecting the rear wheel 132, but also avoid the second muffler 1622 and the fourth muffler 1624 from being damaged in a crash due to excessive protrusion, thereby improving the service life of the muffler 162.

[0043] In this embodiment, the minimum distance between the center of the first projection and the center of the second projection along the height direction of the motorcycle 100 is defined as the height difference H1 of the muffler 162. The height difference H1 of the muffler 162 ranges from 84mm to 126mm, and further, from 95mm to 115mm. In this application, the height difference H1 of the muffler 162 is 105mm. It is understood that the minimum distance between the third projection and the fourth projection along the height direction of the motorcycle 100 is the same as the minimum distance between the first projection and the second projection along the height direction of the motorcycle 100. The above configuration avoids the situation where the distance between the first muffler 1621 and the second muffler 1622, or the third muffler 1623 and the fourth muffler 1624 is too close, which would cause interference between the mufflers 162 during the exhaust process, resulting in excessively high exhaust gas temperature and excessive noise. It also avoids the situation where the distance between the first muffler 1621 and the second muffler 1622, or the third muffler 1623 and the fourth muffler 1624 is too far, which would be detrimental to the arrangement of the mufflers 162. As a result, the noise during exhaust can be reduced, and the driving experience can be improved.

[0044] In this embodiment, a horizontal plane 102 perpendicular to the height direction of the motorcycle 100 is defined. When the motorcycle 100 is traveling horizontally, the lowest points of the front wheel 131 and the rear wheel 132 are both located on this horizontal plane 102. Along the height direction of the motorcycle 100, the projections of the axes of the first muffler 1621, the second muffler 1622, the third muffler 1623, and the fourth muffler 1624 onto the horizontal plane 102 are respectively the first horizontal projection, the second horizontal projection, the third horizontal projection, and the fourth horizontal projection. The first and second horizontal projections are substantially parallel, and the third and fourth horizontal projections are substantially parallel. This parallel arrangement facilitates the connection between the first muffler 1621 and the second muffler 1622, or the third muffler 1623 and the fourth muffler 1624, and the side guard plate 121, thereby improving the connection stability of each muffler 162. Optionally, the first and second horizontal projections can be set to be non-parallel, and the third and fourth horizontal projections can also be set to be non-parallel, so that the distance between the four mufflers 162 is closer at the end near the four ports, which is beneficial to the arrangement of the four ports and the connection between the four mufflers 162 and the four ports, making the overall structure of the motorcycle 100 more compact.

[0045] like Figure 6 and Figure 7As shown, the motorcycle 100 also includes a pedal assembly 17, which includes a rear pedal 171. The rear pedal 171 is fixedly connected to the subframe 112 via a pedal bracket 113. The pedal assembly 17 also includes a pedal mounting member 172, which is fixedly connected to the subframe 112. The pedal bracket 113 is fixedly connected to the subframe 112 via the pedal mounting member 172. The pedal mounting member 172 has mounting holes 1721. The pedal assembly 17 also includes mounting bolts 173, which are fixedly connected to the mounting holes 1721 after passing through the pedal bracket 113. It is understandable that the longer the length of the pedal mounting member 172 in the width direction of the motorcycle 100, the more the rear pedal 171 will protrude outward when the pedal bracket 113 is installed on the subframe 112. The aforementioned "rear footrest 171 protruding outward" refers to the distance between the rear footrest 171 and the subframe 112. That is, the more the rear footrest 171 protrudes outward, the greater the distance between the rear footrest 171 and the subframe 112. When the rear footrest 171 protrudes outward too much, it is easy for the rear passenger to have a poor riding experience when stepping on the rear footrest 171. In addition, the outward protrusion of the rear footrest 171 also makes it easy for the rear footrest 171 to collide with the ground and be damaged when the motorcycle 100 crashes. Specifically, the subframe 112 includes a frame tube 1121, on which a receiving hole 1121a is provided. The receiving hole 1121a and the mounting hole 1721 are coaxially arranged. The mounting bolt 173 also passes through the receiving hole 1121a at least partially and is located inside the frame tube 1121. Thus, the mounting bolt 173 can enter the interior of the frame tube 1121 through the receiving hole 1121a. This allows the length of the foot pedal mounting member 172 in the width direction of the motorcycle 100 to be reduced without affecting the installation of the mounting bolt 173, thus preventing the rear foot pedal 171 from protruding too much outward. Furthermore, the length of the mounting bolt 173 located inside the frame tube 1121 is defined as the insertion length H2. The ratio of the insertion length H2 to the inner diameter R of the frame tube 1121 ranges from 0.28 to 0.42. In this application, the ratio of the insertion length H2 to the inner diameter R of the frame tube 1121 is 0.35. With the above settings, the larger the ratio of the insertion length H2 to the inner diameter R of the frame tube 1121, the longer the insertion length H2 of the mounting bolt 173 is. This means that the length of the foot pedal mounting piece 172 in the width direction of the motorcycle 100 can be set smaller. That is, as the insertion length H2 increases, the length of the mounting hole 1721 can be reduced. This reduces the distance between the rear foot pedal 171 and the frame tube 1121 when the rear foot pedal 171 is mounted on the foot pedal bracket 113, preventing the rear foot pedal 171 from protruding too much outward. This can improve the riding comfort of the rear passenger and also prevent the rear foot pedal 171 from being damaged due to collision with the ground when the motorcycle 100 crashes.

[0046] In this embodiment, the pedal mounting component 172 is fixedly connected to the frame tube 1121 by welding. The side of the pedal mounting component 172 closest to the frame tube 1121 is defined as the abutment surface 104. The pedal mounting component 172 and the frame tube 1121 abut against each other through the abutment surface 104 so that the pedal mounting component 172 and the frame tube 1121 can be welded. The abutment surface 104 is basically consistent with the outer surface of the frame tube 1121, so that the pedal mounting component 172 can fit against the frame tube 1121. This not only facilitates the welding of the frame tube 1121 and the pedal mounting component 172, but also increases the contact area and improves the connection stability between the frame tube 1121 and the pedal mounting component 172. In addition, a positioning part 1722 is provided on the side of the pedal mounting part 172 away from the frame tube 1121. The positioning part 1722 is a boss structure formed by a radial inward recess along the mounting hole 1721. A positioning groove 1131 is provided on the side of the pedal bracket 113 near the pedal mounting part 172. The positioning groove 1131 can cooperate with the boss structure formed by the positioning part 1722. Thus, during the connection process between the pedal bracket 113 and the pedal mounting part 172, the boss structure formed by the positioning part 1722 can provide a guiding and initial fixing function for the pedal bracket 113, thereby facilitating the insertion and fixing of the mounting bolt 173 and improving the assembly performance of the pedal assembly.

[0047] like Figure 6 As shown, the foot pedal bracket 113 is also provided with a side guard plate mounting part 1132, which is fixedly connected to the side guard plate 121; the foot pedal bracket 113 is also provided with a muffler mounting part 1133, which is fixedly connected to the muffler mounting plate 1625. There are two muffler mounting parts 1133, and the two muffler mounting parts 1133 are distributed along the height direction of the motorcycle 100. The side guard plate mounting part 1132 is located below the muffler mounting part 1133; see reference. Figure 2 As shown, when the side guard plate 121 and the footrest bracket 113 are in the installed state, viewed along the width direction of the motorcycle 100, the side guard plate 121 covers the muffler mounting part 1133 and the muffler mounting plate 1625. Through the above arrangement, the footrest bracket 113 can also provide mounting points for fixing the side guard plate 121 and the muffler 162, thereby preventing the muffler 162 from shaking during the operation of the motorcycle 100, thus improving the connection stability of the muffler 162. In addition, the side guard plate 121 covering the muffler mounting part 1133 not only provides protection for the muffler mounting part 1133, but also improves the appearance performance of the motorcycle 100.

[0048] like Figure 8As shown, the motorcycle 100 also includes a transmission assembly 18, which drives the engine 141 and the rear wheel 132, thereby providing power to the rear wheel 132 to drive it to rotate and thus propel the motorcycle 100. Specifically, the transmission assembly 18 includes a sprocket (not shown) and a chain 181. The engine 141 also includes an output shaft (not shown). The sprocket is connected to the output shaft of the engine 141 and is driven by the chain 181 and the rear wheel 132. To protect the sprocket from detachment or damage due to external factors, and because the output shaft of the engine 141 is located close to the driver's leg area, the sprocket may catch the driver's clothing in the gears during rotation with the output shaft of the engine 141, thus threatening the driver's personal safety. Therefore, the body panel 12 also includes a sprocket cover 122, which is fixedly connected to the engine 141. When viewed along the width of the motorcycle 100, the sprocket cover 122 at least partially overlaps with the engine 141, that is, the sprocket cover 122 covers the sprocket.

[0049] like Figure 9 As shown, the motorcycle 100 further includes an electrical component 19 (see reference). Figure 8 Electrical component 19 is primarily used to assist the driver in operating the motorcycle 100. Electrical component 19 includes a push-button switch 191 located on the handlebar 24 (see reference). Figure 8 The control harness 192 and the push-button switch 191 are electrically connected to the engine 141 via the control harness 192, allowing the driver to control the engine 141 via the push-button switch 191. One end of the control harness 192 is connected to the push-button switch 191, and the other end is connected to the engine 141. At least a portion of the control harness 192 is located between the sprocket cover 122 and the sprocket. Viewed along the width direction of the motorcycle 100, the control harness 192 at least partially overlaps with the sprocket and the chain 181. The control harness 192 extends along the height direction of the motorcycle 100 and passes through the sprocket, i.e., the control harness 192 is located between the sprocket cover 122 and the engine 141. During the operation of the motorcycle 100, if the control harness 192 is not secured, it will swing under the vibration of the motorcycle 100, causing it to easily rub against the chain 181, affecting the normal operation of the motorcycle 100 and potentially posing a safety hazard. In this application, a fixing part 1221 is provided on the side of the sprocket cover 122 near the engine 141. The control harness 192 is engaged with the fixing part 1221, thereby preventing the control harness 192 from rubbing against the chain 181 during the motorcycle 100's operation, which can improve the driving safety of the motorcycle 100.

[0050] In this embodiment, the fixing part 1221 can separate the control harness 192 from the chain 181, thereby preventing friction between the control harness 192 and the chain 181. Furthermore, the fixing part 1221 has an opening facing the front of the motorcycle 100. The sprocket cover 122 also includes a blocking part 122, which engages with the control harness 192. The blocking part 1222 has an opening facing the rear of the motorcycle 100. The control harness 192 is located between the blocking part 1222 and the fixing part 1221, thereby restricting the movement of the control harness 192 along the length of the motorcycle 100. Furthermore, the blocking part 1222 and the fixing part 1221 are distributed substantially along the height direction of the motorcycle 100. Two blocking parts 1222 are provided, and the fixing part 1221 is located between the two blocking parts 1222. Viewed along the width of the motorcycle 100, the blocking part 1222 at least partially overlaps with the control harness 192, thereby restricting the movement of the control harness 192 in the width direction of the motorcycle 100 by means of the sprocket cover 122 and the fixing part 1221. With the above arrangement, the fixing part 1221 and the blocking part 1222 can restrict the movement of the control harness 192 in both the length and width directions of the motorcycle 100, thereby preventing the control harness 192 from swaying during motorcycle operation. This prevents the control harness 192 from rubbing against the chain 181 due to swaying, thus improving the driving safety of the motorcycle 100.

[0051] like Figure 10 As shown, in one embodiment, the motorcycle 100 also includes a fuel assembly 21 (see reference). Figure 8 Fuel assembly 21 includes fuel tank 211 (see reference) Figure 8 The fuel tank 211 is primarily used to store the energy required for the operation of the engine 141. The fuel assembly 21 also includes a drain pipe 212 (see reference). Figure 8One end of the drain pipe 212 is connected to the fuel tank 211, and the other end of the drain pipe 212 extends downward to the bottom of the motorcycle 100 and communicates with the external environment, so as to drain rainwater or accumulated water in the fuel tank 211. The end of the drain pipe 212 needs to be set at the lowest possible position to avoid water droplets falling on the engine 141 during the drainage process and causing corrosion. Therefore, the drain pipe 212 extends along the height direction of the motorcycle 100 and the end of the drain pipe 212 is located at the bottom of the motorcycle 100. In this application, to prevent the drain pipe 212 from rubbing against the chain 181 due to shaking during the movement of the motorcycle 100, a water pipe limiting part 1223 is provided on the side of the sprocket cover 122 away from the engine 141. The drain pipe 212 is engaged with the water pipe limiting part 1223, and the opening of the water pipe limiting part 1223 faces the front of the motorcycle 100. The water pipe limiting part 1223 can limit the drain pipe 212 in the width direction of the motorcycle 100. When viewed along the width direction of the motorcycle 100, the water pipe limiting part 1223 and the drain pipe 212 at least partially overlap. Through the above arrangement, the water pipe limiting part 1223 can restrict the movement of the drain pipe 212, thereby preventing the drain pipe 212 from rubbing against the chain 181, thus reducing the wear of the drain pipe 212 and improving the service life of the drain pipe 212.

[0052] Reference Figure 8 As shown, in one embodiment, the suspension assembly 15 also includes a shock absorber 151. The shock absorber 151 has an initial setting at the factory. During the operation of the motorcycle 100, the driver usually needs to adjust the shock absorber 151 multiple times to meet the driver's actual needs. The body panel 12 includes side panels 124 located on both sides of the motorcycle 100. The side panels 124 are at least partially fixedly connected to the subframe 112. Along the width direction of the motorcycle 100, the shock absorber 151 is covered by the side panels 124. To facilitate the driver's adjustment of the shock absorber 151, the side panels 124 are provided with access ports 1241. The body panel 12 also includes a side cover 125. The side cover 125 is at least partially located behind the main frame 111 and in front of the side guard plate 121. The side cover 125 covers the access port 1241 and is bolted to the side panel 124. The side cover 125 also overlaps at least partially with the shock absorber 151, so that the driver can adjust the shock absorber 151 simply by removing the side cover 125, thereby simplifying the maintenance process and improving the maintainability of the motorcycle 100.

[0053] like Figure 8As shown, in one embodiment, during the operation of the motorcycle 100, the engine 141 generates a large amount of heat. After being cooled by the radiator or guided by the airflow of the motorcycle 100 itself, the hot airflow blows backward over the engine 141, heating the metal frame 11. This can easily cause the driver to be burned by the hot frame 11. In this application, the body panel 12 also includes a heat insulation strip 126 located above the engine 141. The heat insulation strip 126 is fixedly connected to the main frame 111. The area where the heat insulation strip 126 is located is the area where the driver's knees rest. Therefore, the heat insulation strip 126 can prevent the driver from directly contacting the hot main frame 111, improving the driver's driving experience. Figure 11 As shown, further, a plane perpendicular to the length direction of the motorcycle and at least partially passing through the heat insulation strip 126 is defined as the transverse plane 101. Along the length direction of the motorcycle 100, the projection of the heat insulation strip 126 onto the transverse plane 101 is called the heat insulation strip projection, and the projection of the main frame 111 onto the transverse plane 101 is called the frame projection. The minimum distance between the outermost edge of the heat insulation strip projection and the frame projection is defined as the protrusion length H3, which ranges from 2mm to 4mm. In this application, the protrusion length H3 is set to 3mm. With the above configuration, the protrusion length indicates that the heat insulation strip 126 can protrude from the main frame 111 along the width direction of the motorcycle 100. Therefore, during the operation of the motorcycle 100, the driver's knees will preferentially contact the heat insulation strip 126, thus preventing the driver's legs from contacting the hot main frame 111, thereby improving the driver's driving experience. It is understood that the "outermost edge of the heat insulation strip projection" mentioned above refers to the side of the heat insulation strip projection furthest from the main frame 111.

[0054] like Figure 12 and Figure 13 As shown, in one embodiment, the vehicle body panel 12 of this application also includes a front skid plate 128, and the motorcycle also includes a headlight 23. The front skid plate 128 is at least partially located below the windshield 123 and at least partially located above the headlight 23. The motorcycle 100 also includes a rearview mirror 25 for observing the driving conditions behind the vehicle (see reference). Figure 8The front guard plate 128 and the windshield 123 are fixedly connected by a rearview mirror 25. Specifically, the rearview mirror 25 basically passes through the front guard plate 128 and the windshield 123 and is fixedly connected to the frame 11 to fix the front guard plate 128 and the windshield 123. Furthermore, the body panel 12 also includes headlight guards 127, of which there are two, and the two headlight guards 127 are distributed along the width direction of the motorcycle 100. The front skid plate 128 and the headlight 23 are at least partially located between the two headlight guards 127. Furthermore, the headlight guards 127, the front skid plate 128 and the windshield 123 distributed along the width direction of the motorcycle 100 are all fixedly connected by a rearview mirror 25, that is, the rearview mirror 25 passes through the headlight guards 127, the windshield 123 and the front skid plate 128 in sequence and is fixedly connected to the frame 11. Understandably, the installation sequence of the three components is as follows: first, connect the windshield 123 and the front skid plate 128; then connect the headlight skid plate 127; and finally, securely connect the three components using the rearview mirror 25. To optimize the above installation steps, as an optional implementation, a windshield snap-fit ​​part 1231 is provided below the windshield 123, and a snap-fit ​​groove 1281 is provided on the front skid plate 128. The windshield snap-fit ​​part 1231 snaps into the snap-fit ​​groove 1281. This design improves the connection stability of the windshield 123 through snap-fit ​​fixing, and the snap-fit ​​groove 1281 also provides positioning for the installation of the windshield 123. This allows the windshield 123 to be initially fixed and positioned by the snap-fit ​​between the windshield snap-fit ​​part 1231 and the snap-fit ​​groove 1281, and then finally fixed after the rearview mirror 25 is installed, thereby improving the assembly performance of the body panel 12. Furthermore, the power assembly 14 also includes an intake manifold 143 (see reference). Figure 14The air intake pipe 143 includes an air intake 1431, and also includes a left air intake 1432 and a right air intake 1433 distributed along the width direction of the motorcycle 100. Therefore, the air intake 1431 includes a left air intake 1431a and a right air intake 1431b, which are distributed along the width direction of the motorcycle 100 and are located on both sides of the front skid plate 128 and the two headlight skid plates 127. Because the headlight skid plates 127 and the front skid plate 128 are located close to the air intake 1431, during the operation of the motorcycle 100, the overlapping part of the headlight skid plate 127 and the front skid plate 128 is prone to warping due to wind resistance. In this application, the front end of the headlight guard plate 127 is provided with a limiting part 1271, and the front end of the front guard plate 128 is provided with a limiting groove 1282. The limiting part 1271 is at least partially located in the limiting groove 1282, so that the front guard plate 128 can provide a limiting function for the front end of the headlight guard plate 127, preventing the front end of the headlight guard plate 127 from bending at the edge due to wind resistance, thereby improving the connection stability of the headlight guard plate 127.

[0055] like Figure 14As shown, the air intake pipe 143 extends substantially along the length of the motorcycle 100, and the air intake 1431 faces substantially towards the front of the motorcycle 100. The air intake 1431 is at least partially located below the headlight 23. As the speed of the motorcycle 100 increases, the air resistance encountered by the motorcycle 100 gradually increases. Since the front of the motorcycle 100 is located on the main windward side, a high-pressure area with high wind pressure is formed at the front of the motorcycle. In this application, the air intake 1431 is located in the high-pressure area, thereby increasing the air intake volume of the air intake 1431 and improving the performance of the motorcycle 100. Specifically, the intake pipe 143 includes a left intake pipe 1432 and a right intake pipe 1433 distributed along the width direction of the motorcycle 100. The left intake pipe 1432 includes a left intake section 1432a and a left vent section 1432b. The left intake section 1432a extends substantially along the length direction of the motorcycle 100 and is located in front of the left vent section 1432b. The left vent section 1432b communicates with the air filter 142. The right intake pipe 1433 includes a right intake section 1433a. The right air intake 1433a extends along the length of the motorcycle 100, and the right air intake 1433a is located in front of the right air intake 1433b. The right air intake 1433b is connected to the air filter 142. The left air intake 1432b and the right air intake 1433b both extend along the width of the motorcycle 100. The left air intake 1432a and the left air intake 1432b are integrally formed, and the right air intake 1433a and the right air intake 1433b are integrally formed. Along the height direction of the motorcycle 100, the projection of the left air intake 1432a onto the horizontal plane 102 extends substantially along the first straight line 203, and the projection of the right air intake 1433a onto the horizontal plane 102 extends substantially along the second straight line 204. An angle β is formed between the first straight line 203 and the second straight line 204, and the angle β ranges from 14° to 22°; in this application, the angle β is 18°. With this arrangement, the angle β makes the distance between the air intake of the left air intake pipe 1432 and the air intake of the right air intake pipe 1433 in the width direction of the motorcycle 100 closer, thereby ensuring that both air intakes are located within a high-pressure area, thus increasing the air intake volume and improving the performance of the motorcycle 100.

[0056] like Figure 15As shown, in this embodiment, the power assembly 14 also includes a connector 144, which is basically tubular. The connector 144 is located at the connection between the air filter 142 and the air intake pipe 143. The connector 144 is detachably connected to the air filter 142 by bolts. The connector 144 is also detachably connected to the air intake pipe 143 by snap-fit. After natural air enters the air intake pipe 143, it enters the air filter 142 through the connector 144. Along the height direction of the motorcycle 100, there is a height difference between the connection between the left air intake 1432a and the left ventilation 1432b and the air intake 1431, so that the left air intake 1432a is inclined downward. When water enters the air intake 1431 or when condensation occurs due to gas compression, the water can flow out naturally from the air intake under the action of gravity, thereby preventing water from entering the air filter 142 and causing damage to the air filter 142. Specifically, a longitudinal plane 103 perpendicular to the width direction of the motorcycle 100 is defined. The projections of the left air intake 1432a and / or the right air intake 1433a onto the longitudinal plane 103 extend substantially along a predetermined straight line 205. An angle γ is formed between the predetermined straight line 205 and the horizontal plane 102. The opening of this angle γ faces the front of the motorcycle 100, and the angle γ ranges from 12° to 18°. In this application, the angle γ is set to 15°. This design avoids both excessively large angles β, which could hinder air intake to the air filter 142 and affect the normal operation of the motorcycle 100, and excessively small angles β, which could cause water to enter the air filter 142 through the air intake 1431 and damage the air filter 142. This improves the service life of the air filter 142 and enhances the operational stability of the motorcycle 100.

[0057] like Figure 16 , Figure 17 and Figure 18As shown, in this embodiment, the air filter 142 may need to be disassembled during the maintenance of the motorcycle 100. Before disassembling the air filter 142, the intake pipe 143 needs to be removed first. Since the intake pipe 143 is covered by multiple body panels 12, the disassembly of the intake pipe 143 is cumbersome and time-consuming, resulting in low maintenance efficiency of the motorcycle 100. In this application, the connector 144 includes a mounting part 1441 and a snap-fit ​​part 1442. The mounting part 1441 is at least partially located inside the air filter 142 and is detachably connected to the air filter 142 by bolts. The intake pipe 143 is at least partially located inside the connector 144 and is snap-fitted to the snap-fit ​​part 1442. With the above configuration, when it is necessary to disassemble the air filter 142, the bolts between the air filter 142 and the connector 144 are first removed, and the snap-fit ​​between the connector 144 and the intake pipe 143 is released, thereby allowing the connector 144 to be removed. Thus, the air filter 142 can be removed without removing the intake pipe 143. With the above-described configuration, the air filter 142 and the intake pipe 143 are connected separately via the connector 144, allowing the air filter 142 to be removed independently. This improves the efficiency of air filter 142 installation and removal, facilitates maintenance of the air filter 142 or other components of the motorcycle 100, and enhances the assembly and maintenance performance of the motorcycle 100. Furthermore, the intake pipe 143 is provided with an abutment portion 1434, which provides positioning for the installation of the connector 144 and the intake pipe 143. When the intake pipe 143 extends into the connector 144, the abutment portion 1434 abuts against the connector 144 to prevent the intake pipe 143 from extending too far and causing a failure in the connection between the intake pipe 143 and the connector 144. In addition, a buffer part 1443 is provided on the connector 144. The buffer part 1443 is annular and surrounds the air intake pipe 143 and the connector 144. The buffer part 1443 is usually made of elastic material such as rubber. When the air intake pipe 143 and the connector 144 are engaged, the buffer part 1443 can block the gap between the air intake pipe 143 and the connector 144 through its own deformation, thereby achieving a seal between the air intake pipe 143 and the connector 144. This prevents air leakage at the connection between the air intake pipe 143 and the connector 144, which would reduce the air intake volume of the air filter 142. It also prevents dust from entering the air filter 142 through the gap and affecting the working efficiency of the air filter 142.

[0058] like Figure 19 and Figure 20 As shown, the frame 11 also includes an auxiliary mounting bracket 114, which is located behind the subframe 112 and fixedly connected to it. The motorcycle 100 also includes a seat assembly 22, which includes a main seat 221 (see reference). Figure 8The vehicle frame 11 also includes a main seat cushion 221 and a secondary seat cushion 222 located behind the main seat cushion 221. The main seat cushion 221 is located above the subframe 112 and is fixedly connected to the subframe 112. The secondary seat cushion 222 is for rear passengers to sit on. The secondary seat cushion 222 is located above the auxiliary mounting bracket 114 and abuts against the auxiliary mounting bracket 114. The vehicle frame 11 also includes a rear bracket 115, which is located behind the auxiliary mounting bracket 114 and connected to the subframe 112. The secondary seat cushion 222 is also at least partially located above the rear bracket 115 and is fixedly connected to the rear bracket 115.

[0059] In this embodiment, the seat cushion assembly 22 further includes a seat cushion lock 223 and a seat cushion cable 224. The seat cushion lock 223 is used to unlock or lock the seat cushion assembly 22, and the seat cushion cable 224 is used to control the opening and closing of the main seat cushion 221. The auxiliary mounting bracket 114 is provided with a cable fixing part 1141 and a seat cushion lock fixing part 1142. The seat cushion cable 224 is fixedly connected to the auxiliary mounting bracket 114 through the cable fixing part 1141, and the seat cushion lock 223 is fixedly connected to the auxiliary mounting bracket 114 through the seat cushion lock fixing part 1142. The auxiliary mounting bracket 114 is also provided with a strap fixing part 1143. The seat assembly 22 also includes a seat strap 225. The seat strap 225 is located at the front end of the auxiliary mounting bracket 114. There are two strap fixing parts 1143, and the two strap fixing parts 1143 are distributed along the width direction of the motorcycle 100. The two ends of the seat strap 225 are fixedly connected to the two strap fixing parts 1143 respectively, so that the seat strap 225 can form a loop. The seat strap 225 surrounds the sub-seat 222 and is at least partially located above the sub-seat 222. When the rear passenger sits on the sub-seat 222, the rear passenger can grab the seat strap 225 to provide a safe grip point, thereby preventing the rear passenger from falling off the motorcycle 100 during the motorcycle 100's operation.

[0060] The auxiliary mounting bracket 114 is also equipped with a seat support point 1144, which is located behind the seat strap 225. The seat support point 1144 protrudes upward along the height direction of the motorcycle 100 and abuts against the sub-seat 222. Therefore, when the sub-seat 222 is installed, the seat support point 1144 provides support for the sub-seat 222, thereby improving the connection stability between the sub-seat 222 and the frame 11. The seat support point 1144 also ensures that the seating area of ​​the sub-seat 222 is basically horizontal, which is beneficial for rear passengers and improves their riding experience. Specifically, at least two seat support points 1144 are provided, distributed along the width direction of the motorcycle 100. This allows the two seat support points 1144 to share the pressure on the sub-seat 222, making the connection between the sub-seat 222 and the auxiliary mounting bracket 114 and the tail bracket 115 more stable. Furthermore, the cable fixing part 1141 is located to the right of the strap fixing part 1143, the seat lock fixing part 1142 is located below the strap fixing part 1143, and the seat support point 1144 is located behind the strap fixing part 1143. Through the above arrangement, the auxiliary mounting bracket 114 integrates the cable fixing part 1141, the seat lock fixing part 1142, the strap fixing part 1143, and the seat support point 1144, thereby reducing the number of fixing points on the frame 11, simplifying the mounting structure of the frame 11, and improving the space utilization of the frame 11. In addition, the auxiliary mounting bracket 114 is also provided with several weight-reducing holes 1147, located between the strap fixing part 1143 and the seat support point 1144, thereby reducing the weight of the auxiliary mounting bracket 114 and improving the lightweight design of the frame 11.

[0061] As one implementation, the auxiliary mounting bracket 114 also includes an electrical component fixing part 1145, located behind the seat cushion strap 225. The electrical component assembly 19 includes a diagnostic box 193, which is mainly used to help repair personnel quickly identify the nature and location of the fault. The diagnostic box 193 is detachably connected to the auxiliary mounting bracket 114 via the electrical component fixing part 1145. In this application, the diagnostic box 193 is located below the sub-seat cushion 222. Repair personnel only need to remove the sub-seat cushion 222 to diagnose vehicle faults through the diagnostic box 193, thereby reducing the number of parts that need to be removed during the repair process and improving repair efficiency. It should be noted that in this application, the diagnostic box 193 refers to an OBD (On-Board Diagnostics) box. In addition, the auxiliary mounting bracket 114 is also provided with a wiring harness grounding point 1146, which is located on the left side of the strap fixing part 1143. The electrical assembly 19 also includes a ground wire 194 for grounding the electrical components of the motorcycle 100. The wiring harness grounding point 1146 is used to connect the ground wire 194. The ground wire 194 is electrically connected to the subframe 112 through the wiring harness grounding point 1146. The setting of the wiring harness grounding point 1146 ensures the stable operation of the vehicle circuit by connecting the ground wire of the whole vehicle wiring harness to the metal part of the frame 11, thereby ensuring the stability of the circuit and avoiding the occurrence of overheating of the line or malfunction of the electrical components due to poor wiring harness contact or circuit instability. In addition, it can also effectively prevent the positive line from directly contacting the vehicle body, thereby improving the safety of the whole vehicle.

[0062] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
